The Amazon sales rank (ASR) provides an indication of the popularity of a product sold on any Amazon locale. It is a relative indicator of popularity that is updated hourly. Effectively, it is a "best sellers list" for the millions of products stocked by Amazon.[134] While the ASR has no direct effect on the sales of a product, it is used by Amazon to determine which products to include in its bestsellers lists.[134] Products that appear in these lists enjoy additional exposure on the Amazon website and this may lead to an increase in sales. In particular, products that experience large jumps (up or down) in their sales ranks may be included within Amazon's lists of "movers and shakers"; such a listing provides additional exposure that might lead to an increase in sales.[135] For competitive reasons, Amazon does not release actual sales figures to the public. However, Amazon has now begun to release point of sale data via the Nielsen BookScan service to verified authors.[136] While the ASR has been the source of much speculation by publishers, manufacturers, and marketers, Amazon itself does not release the details of its sales rank calculation algorithm. Some companies have analyzed Amazon sales data to generate sales estimates based on the ASR,[137] though Amazon states:

Goodreads is a "social cataloging" website founded in December 2006 and launched in January 2007 by Otis Chandler, a software engineer, and entrepreneur, and Elizabeth Chandler. The website allows individuals to freely search Goodreads' extensive user-populated database of books, annotations, and reviews. Users can sign up and register books to generate library catalogs and reading lists. They can also create their own groups of book suggestions and discussions. In December 2007, the site had over 650,000 members and over 10 million books had been added. Amazon bought the company in March 2013.[100]

After locating the product in Amazon’s catalog, a seller will be prompted to enter information about its quality. It’s important to be as truthful and accurate as possible when describing the item as one of the following: new, used-like new, used-very good, used-good or used-acceptable. You can also provide a note with pertinent details about the item. For example, you can explain that a book is in good condition save a few folded pages.
In July 1995, the company began service as an online bookstore.[31] The first book sold on Amazon.com was Douglas Hofstadter's Fluid Concepts and Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought.[32] In the first two months of business, Amazon sold to all 50 states and over 45 countries. Within two months, Amazon's sales were up to $20,000/week.[33] In October 1995, the company announced itself to the public.[34] In 1996, it was reincorporated in Delaware. Amazon issued its initial public offering of stock on May 15, 1997, at $18 per share, trading under the NASDAQ stock exchange symbol AMZN.[35]

Amazon, seeing the obvious opportunity here, reportedly outbid none other than Google to become Twitch’s parent company three years later, with the AWS infrastructure a big part of why Twitch CEO Emmett Shear decided to take the deal. Now, four years later, Twitch has outlasted both YouTube and Facebook’s attempts to snatch away its market share and, given the popularity of titles like Epic Games’ Fortnite, has become an even more integral fixture of modern online life and youth culture. Amazon has more recently integrated Twitch into its Prime subscription, giving subscribers free games and complementary channel subscriptions.

Shelfari was a social cataloging website for books. Shelfari users built virtual bookshelves of the titles which they owned or had read and they could rate, review, tag and discuss their books. Users could also create groups that other members could join, create discussions and talk about books, or other topics. Recommendations could be sent to friends on the site for what books to read. Amazon bought the company in August 2008.[100] Shelfari continued to function as an independent book social network within the Amazon until January 2016, when Amazon announced that it would be merging Shelfari with Goodreads and closing down Shelfari.[102][103]

Customers will find products like the card game Codenames (4.8 stars, with more than 2,000 customer reviews), which 88% of reviewers rated 5 stars, and a Lodge 3.5 Inch Cast Iron Mini Skillet (4.4 stars, with more than 10,900 customer reviews), which 76% of reviewers rated 5 stars. Of course, Amazon 4-star shoppers can also find Amazon devices like the Echo Spot (4.5 stars, with more than 5,600 customer reviews), and the Fire TV Stick (4.4 stars, with more than 197,000 customer reviews). Customers can test-drive dozens of Amazon devices and smart home accessories that work with Alexa, and shop a curated selection of speakers, fitness tech, and other highly rated consumer electronics.

The first Echo came out in late 2014 as a Prime member exclusive, but in the four short years since, Amazon has developed dozens of different smart home products that revolve around the speaker and voice assistant format. Today, thousands of products integrate with the company’s Alexa platform to make use of its voice search and query capabilities. Just as it once foresaw e-commerce, streaming, and cloud computing as the future of the internet, Amazon saw AI as not just something that could live within the smartphone — as Apple established with Siri and Google with its Assistant — but also in the home.

Amazon runs data centers for its online services and owns generators or purchases electricity corresponding to its consumption, mostly renewable energy.[139] Amazon contracted with Avangrid to build and operate the first wind farm in North Carolina to power Amazon's Virginia data centers. The wind farm was built and began operating in December 2016 despite opposition from President Trump and some North Carolina Republican legislators.[140][141][142][143][144]

Amazon Studios, which was founded in 2010 to compete with Hulu and Netflix in original programming, has become a powerhouse in Hollywood, taking home both Emmys and Oscars and growing into a staple of the modern entertainment diet of many Americans. Rounding out its position in digital media is the FireTV streaming device, which Amazon first launched in 2014 to compete with Apple, Roku, and other set-top box makers. The product has since been shrunk into a skinny HDMI stick — Amazon still sells the box and now also a small, square-shaped Fire TV Cube — and it remains one of the best-selling consumer electronics devices on Amazon.com.
